The vertical measurement displays how steep the roof is and contributes to the overall pitch ratio. It’s essential to ensure that these measures are as precise as potential, as even minor inaccuracies can affect the general pitch and consequently, the roof's efficiency.
Once both the rise and run measurements are established, the pitch may be calculated by forming a ratio. This course of would possibly include simple mathematical operations. For instance, if the vertical rise is 5 feet and the horizontal run is 12 ft, the pitch ratio would correspond to five:12. This fraction supplies clear insight into the roof's design.
